The paper proposes an approach to security enforcement in disruption-and delay-tolerant networks (DTNs) suitable for emergency and crisis setting. Comparing with traditional networks, DTNs have many unconventional constraints such as long delays, high packet drop rates, unavailability of central trusted entity etc. Under such constraints existing security protocols do not work or not feasible. We propose an approach suitable for combining identity and attribute based encryp-tions (IBE and ABE) with subjective logic based trust model to provide adaptable trust-aware security solutions for wireless DTNs.
